Problems solved by technology

AF coated glass is coated with a layer of chemical materials on the outer surface of the glass to reduce the surface tension of the glass, so that the glass has strong hydrophobicity, oil resistance and fingerprint resistance. Bacteria will grow on the surface, which will affect people's health. At present, the demand for AF coated glass with antibacterial effect is gradually increasing in all walks of life.
For bacteria problems such as touch screens, the common method is to use alcohol and ultraviolet light for disinfection and sterilization, but both alcohol and ultraviolet disinfection have certain limitations, and corresponding alcohol materials or ultraviolet equipment are required

Abstract

The invention provides a method for preparing AF coated glass with antibacterial effect, comprising the following steps: S1, ultrasonically cleaning the glass substrate with a solvent or cleaning agent, then rinsing with deionized water, and blowing dry with nitrogen; S2, Coating a layer of SiO on the glass substrate by vacuum coating 2 Film base layer; S3. Add nano-silver to the anti-fingerprint agent, and spray the treated anti-fingerprint agent evenly onto the SiO on the surface of the glass substrate by a spraying machine. 2 On the base layer of the film, then dry the glass substrate, take it out and cool it, so as to form an antibacterial and anti-fingerprint layer; S4, disperse SiO in a solvent 2 Particles and nano-silver are prepared into an antibacterial coating solution, and the antibacterial solution is evenly sprayed on the antibacterial and anti-fingerprint layer of the glass substrate by a spraying machine, and then the glass substrate is dried, taken out and cooled to form an antibacterial SiO 2 film layer. The coated glass of the invention has anti-fingerprint and antibacterial effects.

Description

technical field [0001] The invention belongs to the technical field of glass coating, and in particular relates to a preparation method of AF coated glass with antibacterial effect. Background technique [0002] With the continuous development of social economy and the continuous improvement of human living standards, glass has developed from a single lighting, perspective and shelter from wind and rain to multifunctional glass products with various special purposes. AF coated glass is coated with a layer of chemical materials on the outer surface of the glass to reduce the surface tension of the glass, so that the glass has strong hydrophobicity, oil resistance and fingerprint resistance. Bacteria will grow on the surface, which will affect people's health. At present, the demand for AF coated glass with antibacterial effect is gradually increasing in all walks of life. For bacteria problems such as touch screens, the common method is to use alcohol and ultraviolet to disi...
